Re: Is this sprocket too worn?
i can only see a pic of a front sprocket and to me it looks like new so no need to change it.
there is a simple test on rear sprockets/chains. if you can insert a pencil between the chain and sprocket tooth then your chain and sprockets need changed as they are fubar.
visual inspection, if the teeth on a sprocket are 'hooked' then they need changed.
i have said it before but a scottoiler is the key to chain & sprocket life. if you have OCD then use 'dry lube' and put up with shorter chain & sprocket life.
cracking the throttle open to get your kicks also reduces the life of tyres, chain & sprockets.
